Aberdeen Township is a township situated on the Jersey Shore in Monmouth County, in the U.S. state of New Jersey. The township is located within the Raritan Valley region and is a part of the New York Metropolitan Area, bordering both Old Bridge Township, New Jersey, in adjacent Middlesex County, New Jersey, as well as Staten Island in New York City. As of the 2020 United States census, the township's population was 19,329, its highest decennial count ever and an increase of 1,119 (+6.1%) from the 2010 census count of 18,210, which had in turn reflected an increase of 756 (+4.3%) from the 17,454 recorded at the 2000 census.

Aberdeen Township was part of the Bayshore Regional Strategic Plan, an effort by nine municipalities in northern Monmouth County to reinvigorate the area's economy by emphasizing the traditional downtowns, residential neighborhoods, maritime history, and natural environment of the Raritan Bay coastline. The plan has since been integrated into the county's 2016 Master Plan. Aberdeen has worked with neighboring Matawan to build transit-oriented development around the Aberdeen-Matawan train station.

Those who settled in this area developed into the Lenni Lenape Native Americans. About the year 1000, an agricultural society developed, and small villages dotted what was to become New Jersey. The Lenape began a westward retreat in the face of European settlement and disease beginning in the late seventeenth century, beginning in Monmouth County by the mid-eighteenth century. Although the Lenape presently live in Ontario and Oklahoma, their legacy survives in such names as Mohingson, Luppatatong and Matawan Creeks and Raritan Bay.

The earliest known attempt at European settlement was in 1650 when the south side of Raritan Bay was purchased from the Lenni Lenape by the New Netherland Colony.

The earliest English land grant in New Aberdeen was in 1677 when Sir George Carteret granted 36 acres (150,000 m) to Jonathan Holmes. This is in present-day Oakshades on Mohingson Creek.

Matawan Township changed its name in 1977 to Aberdeen Township, which harkened back to the name of the portion of Monmouth County referred to by Scottish settlers as "New Aberdeen." New Aberdeen included the Northern portions of Monmouth County in the 1680s settled by Quakers and Presbyterians who fled Scotland to avoid religious persecution.

In 1684, Surveyor General Thomas Rudyard received a grant of 1,038 acres (4.20 km) on Raritan Bay and Matawan Creek, the present location of Cliffwood and Cliffwood Beach. Owing to Rudyard's high office, this was quite controversial, and in 1685, the Board of Proprietors issued an order regarding the laying out of land. Section 7 addressed questionable activity such as Rudyard's, and he sold his land to his son-in-law, Samuel Winder.

The 1680s saw an influx of Scottish immigrants fleeing religious persecution in response to a 1683 book by George Scott extolling the virtues of Scottish settlement in East Jersey. In 1701, a village site of 100 acres (0.40 km) was granted by the Proprietors to 24 Scottish settlers of the area. These men and six others also purchased a landing site on Matawan Creek. The village site eventually came to be called Mount Pleasant, and the landing, as it became an important shipping point for the produce of Middletown Township, became Middletown Point. A third, very scattered settlement developed in the eighteenth century west of Matawan Creek, and was called Matawan or Matavan.

In 1693, what was to become Aberdeen Township became part of Middletown Township which, at the time, consisted of what is now Aberdeen, Holmdel Township, Hazlet Township, Middletown (including Sandy Hook), Matawan Borough, Keyport, Union Beach, Keansburg, Atlantic Highlands, Highlands and a sliver of Colts Neck Township. A portion of the township that extended as far northwest as Cheesequake Creek, was ceded to Middlesex County in 1710.

Middletown was considered too large and unwieldy, and legislation was passed in February 1848 that took the western half of Middletown Township to create a new municipality, Raritan Township (now Hazlet Township).

Legislation sponsored by Assemblyman Beers passed the State General Assembly and Senate, was signed by Governor of New Jersey William A. Newell, and on February 23, 1857, Matavan Township was incorporated from portions of what was then Raritan Township. This included the village of Middletown Point, Mt. Pleasant, and Matavan. The Township was named for the creek as well as the village of Matavan. The spelling of "Matawan" or "Matavan" had been interchangeable, however, when the act was published "Matavan" had been used, which may derive from a Lenape word meaning "where two rivers come together". It may also originate from the Southern Unami Matawonge, "bad riverbank" or "bad hill", a possible reference to bluffs along Raritan Bay which were subject to erosion and collapse prior to the construction of a seawall in the 1970s. Another possible source is Matawan, Northern Unami for "bad fog", which may have referred to fog generated on Raritan Bay.

In 1865, due to postal confusion with Middletown, the Middletown Point post office was renamed "Matawan", to reflect the name of the Township. This section is the present downtown area of Matawan Borough. In 1882, the spelling of the Township was officially changed to "Matawan".

A small railroad station was erected along the New York and Long Branch Railroad tracks at a point called Hutchler's Crossing in 1875. Soon known as the Cliffwood Station, it operated on Cliffwood Avenue until the station closed in 1932.

In 1885, the Cliffwood post office was established and the name of the old Matavan settlement passed into obsolescence. Matawan was formed as a borough on June 28, 1895, from portions of Matawan Township, based on the results of a referendum held that day. Matawan expanded with portions of Matawan Township in 1931 and 1933.

In response to demand, a post office was established at Mount Pleasant in 1889. As that name was in use elsewhere, a new name was needed. "Freneau" was chosen, in honor of Philip Morin Freneau, the "Poet of Revolution," and a former Mount Pleasant resident who is buried in the area. This post office has since been closed.

Cliffwood Beach, formed in the 1920s, was originally a resort community until after World War II when year-round homes were the norm. River Gardens developed in the late 1940s. Strathmore was built starting in the early 1960s by Levitt & Sons, marketed as a higher-end version of the Levittown communities that the firm was known for. The 2,000 new homes in the development led to a jump in the township's population of 10,000 over the decade, a jump of more than 140%.

On November 8, 1977, the residents of Matawan Township voted to change the name of the Township to create a community identity separate from that of Matawan Borough. The residents voted to call their community Aberdeen Township. Officials believed the new name would draw attention to the Township, as it is listed first alphabetically among New Jersey's municipalities.

Today, Aberdeen is a suburban township of 5.4 square miles (14 km) containing a mix of residential, light industry and shopping centers. Sections of the township include Cliffwood, Cliffwood Beach, Freneau, Oakshades, River Gardens, Strathmore, Santa Fe Junction and Woodfield. Three postal ZIP Codes serve the township: 07721, 07735, and 07747.

The Township is served by two volunteer fire companies, the Aberdeen Township Hose and Chemical Co. No. 1, organized in 1918, and the Cliffwood Volunteer Fire Co., organized in 1927. The Aberdeen Township Hose and Chemical Co. No. 1 marked its 100th anniversary on June 10, 2018, with a celebration at Lloyd Road Park and a parade along Lloyd Road. Two volunteer First Aid Squads response to the community's emergency medical needs; the Aberdeen Township First Aid and Rescue Squad, organized in 1954, and the South Aberdeen Emergency Medical Service, organized in 1970. A full-time Police Department was established in 1935.

The Henry Hudson Trail is a 9-mile (14 km) paved trail built on a former Central Railroad of New Jersey right-of-way and extending from Aberdeen Township east to Atlantic Highlands.

According to the United States Census Bureau, the township had a total area of 7.77 square miles (20.13 km), including 5.45 square miles (14.10 km) of land and 2.33 square miles (6.03 km) of water (29.95%).

The township is broken into two non-contiguous sections, with a small wedge-shaped exclave on the township's southwest corner separated from the rest of the township by a portion of Matawan on the opposite side of Route 79.

Cliffwood Beach (2010 Census population of 3,194) and Strathmore (2010 population of 7,258) are unincorporated communities and census-designated places (CDPs) located within Aberdeen Township. Other unincorporated communities within Aberdeen Township include Cliffwood and Henningers Mills.

The township borders Hazlet Township, Holmdel Township, Keansburg, Keyport, Marlboro Township and Matawan in Monmouth County; and Old Bridge Township in Middlesex County. The borough has a maritime border with Staten Island in New York City.
